CAMERA.

Application led August 19,

To all @07mm it may concern:

Be it known that I, FRANKLIN M. Cossrrfr, a citizen of the United States, and a resident of the city of Binghamton, county of Broome, and State of New York, have invented certain new and useful Improvements in Cameras, of which the followinoP is a specification, reference being had to the accompanying drawings.

It is the purpose of this invention to provide a camera with devices whereby the photographer may conveniently and quickly produce upon the successive exposures of the sensitive film, such record or data as may be .applicable thereto.

In the drawings hereof I show the invention as applied to a folding film-roll camera and I also show only such parts of the apparatus as are necessary for a clear understanding of the construction and method of operation of the invention. It will be understood that suitable obvious changes being made, the invention is applicable to practically all forms of camera. Furthermore the relative size of the parts and the construction of the camera illustrated in the drawings form no essential part of the invention.

In the drawings Figure l is a longitudinal sectional view, broken away, of a camera taken through the center of the devices forming the subject matter of this application, which are in their operative position; Fig. 2 is a view similar to Fig. l, showing the parts constituting the invention in their projected position ready for the application thereto of the matter which is to constitute the record or data; Fig. 3 is anv elevation, broken away, of one side of a camera showing an endwise view of the devices constituting this invention; Figs. 4, 5 and 6 are views corresponding to Figs. 1, 2 and 3 and showing a modilied construction of the invention; Figs. 7, 8 and 9 are views corresponding to Figs. l, 2 and 3 and showing still another modified construction of the invention.

Referring first to Figs. 1, 2 and 3, l, l, represent the two side pieces of the camera, 2 the camera back, shown in this case as removable, 3 the sensitive iilm, 4 the black paper backing therefor, 5 one of the springs Specification of Letters Patent.

which are usually supported by the removable back and which press the edges of the .film and black paper into the focal plane, one only of these springs being shown here. G is a light-tight hollow casino built into the side vof the camera l anc projecting somewhat into its interior, so that its inner part shall properly register with the margin of the film. Vithin this case is a hollow sliding frame 7 at the outer end whereof is a light-excluding slide 8 and in its upper and inner part is a ground glass, translucent or transparent celluloid or equivalent surface or tablet 9, upon which writing in pencil or ink may be made. l0 (see Fig. 3) is a recess cut in the edge of the camera, bounded at each end by abutments ll, 11, to afford a vacant space for the convenient writing upon the ground glass or similar tablet 9. l2 is a pin, or equivalent stop, set in the bottom of the frame 7, which works through a groove, or its equivalent 13, made in the bottom of the fixed casing 6.

The operation of the parts thus far described is as follows:

f the photographer does not care to make any record of the exposure, then he leaves all the parts in the position shown in F ig. l and proceeds in the usual way.

f, however, he does desire a'record, he takes hold of the laterally projecting end f the hollow frame or slide 7 and pulls it out into the position shown in Fig. 2. It will be noted that in so doing the stop 12 will limit the outward slide T at the time when the ground glass 9,V or its equivalent, has become sufliciently eX- posed upon the outside of the camera, constituting, as it were, a bottom for the recess l0 and that the end 7 of the slide will preclude the entrance of light to the edge of the film. The operator now writes upon the exposed surface of the ground glass 9 such data as he desires shall appear upon the negative and thereupon presses the hollow slide 7 backwardly again into the camera until its primary position is attained as shown in Fig. l. Thereupon the slide 8 of the hollow frame 7 is withdrawn, permitting the light to enter through it for such time, ordinarily from two to say five seconds, as may be necessary to effect, according movement of the to well known processes, the transference from the ground glass or similar surface or tablet, of the writing or record made thereon to the edge or marginal part ot the photographic tilm. The slide S is then returned to primary position.

In Figs. d, 5 and 6 I show a modiiied construction in which like reference numerals indicate like parts. In these iigures 14 represents the exterior lixed casing similar to the casing 6 ot Figs. 1, 2 and 3, made, however, on the are of a circle and within it a similarly shaped hollow .trame 15 swings, in effect substantially the same as the sliding movement ot' the trame 7 in Figs. 1, 2 and 3.

In this construction 16 is the ground glass or equivalent tablet and 17 is a slide similar to the slide 6 in Figs. 1, 2 and 3. This segmental hollow :trame 15 is rigidly tastened to a swinging plate 18 which is hinged or pivoted at 19 to the corner ot the camera. 20 is an automatically acting shutter controlled by a spring 21 and pivoted at Q2.

'I he operation of this inodilied form is as follows:

The operato desiring to make his record takes hold oi the projecting end of the segmental hollow irame 15 and pulls it outwardly, whereupon it and the swinging bar or plate 18 upon which it is supported, swing outwardly and upwardly upon the hinge 19, until it assumes the position shown in Fig. 5, whereupon the operator writes upon the exposed surface oi the ground glass 16 such data as he desires shall be recorded. During the outward movement of the segmental frame 15, as soon as its inner end moves beyond the free edge oiv the automatic shutter 20, it, under the action oii the spring 21, will follow the outwardly moving hollow frame until. its tree edge iin-ally rests within the recess 23 in the liked casing, effectively cutting off the entrance ot light.

After the matter to be recorded has been produced upon the exposed surface ot the ground glass tablet 16, the device is then swung backwardly again entering the fixed casing and into the position shown in Fig. 1, during which operation the automatic shutter 29 is shoved out or" the way. The slide 17 is nowdrawn, light is admitted and the impression made upon the margin oi the. ilm, the same as before.

Figs. 7, 6 and 9 show still another modiication. In them like reference numerals indicate like parts the same as before. In this construction 24; represents a lined lightexcluding casing similar to the casing 6 ot' Fig. l and 141 o'r Fig. el. 25 is the automatically acting shutter resembling the shutter 2O of Fig. 4, which is actuated by a spring 26 similar to the spring 21 of Fig. 4, but in this case the slide 27 which carries the ground glass or equivalent surface or tablet 28 1s not hollow and is made entirely removable from the camera, which may be a convenience to the operator in writing the data upon 'the plate '28. is seen in Figs. 7 and S, the slide 27 is composed or a met-al or wooden outer part with a rectangular portion or liange and the inner part composed oi ground glass or similar tablet. These parts are, in the example shown, connected to each other by a tongue and groove joint.. T he liront edge oi: the ground plate or tablet is pre'lerably rounded oil as shown in Figs. 7 and 8, so as not to catch against, on the contrary to smoothly slide beneath the edges ot the lilm and black paper when the slide is 'ie-introduced int-o the camera.

The operation is as iiollows:

Upon withdrawing the slide Jfrom the camera 'for the purpose or writing thereon the matter to form the record, the automatic shutter 25 under the action of the spring 26 follows the receding slide closes lighttight within the recess 29, shown in the upper member ot the tired casing 24. The slide being` removed, wholly desired, from the camera, the matter which is to 'form the record is written thereon, during which time the light is excluded by the n .tomatic shutter. Upon ro-introducing the slide, igs 'front end striking against the shutter 25, presses it out ot the way, but by tl time the lighttransinitting camera, so that lass QS is entr-"c i, within the the .voozlen or other back part et the slit-.e 27 prevents the admission of light. Bitter it has been thoroughly introduced, the opening oi the door 3() by means of the thumb clip 31, otherwise, es the ca-e may be, will permit the ci tre-.nce oi light wiJ h the result bei' re described. rFhe door 30 is hinged to the came 'a as at 3Q and. is normally maintained in closed position by springs 33.

t will be obvious to those who are t.,niiliar with such matters that the three trate-fl a l described, in which t ie invention may be made, are exemples only many that can be employed and I therefore do not limit myself in any respect to the de: construction illustrated cnil described, nor is it essential tiat the apparatus he st ructed in such manner as to produce the data upon one o? tie side edges o'ff the negative.
